1 Claim. 1

A further object is to facilitate the use of a.

bed-pan by a bedridden patient without subjecting the patient to discomfort.

The above and other objects may be attained by employing this invention which embodies among its features a lift frame adapted to rest on the frame of a hospital bed, a trunk supporting and elevating frame pivoted at one end intermediate opposite ends of the lift frame and adapted to overlie the head end of the lift frame, a notched supporting bar pivoted at one end to each side of the trunk supporting and elevating frame intermediate its ends, pins projecting laterally from opposite sides of the lift frame near the head end thereof for entrance into the notches in the supporting bars, a lift sheet extending transversely of the lift frame between the foot end and the trunk supporting and elevating frame and a lift sheet extending transversely of the trunk supporting and elevating frame.

Other features include a removable sheet extending transversely of the lift frame adjacent the pivotal point of the trunk supporting and elevating frame, and the pivots of the trunk supporting and elevating frame substantially coinciding with the pivots of the trunk supporting and elevating frame of the bed whereby the trunk supporting and elevating frame of the lift frame may be moved in unison with that of the bed frame.

In the drawings:

Figure 1 is a plan View of an invalid lift embodying the features of this invention and showing the same mounted on a hospital bed;

Figure 2 is a side view of Figure 1;

Figure 3 is a view similar to Figure 2 i lustrating the trunk supporting and elevating frame of the bed in elevated position, with the trunk supporting and elevating frame of the lift frame resting thereon;

Figure 4 is a fragmentary enlarged end view of the lift frame, showing portions in section to more clearly illustrate certain details of construction;

Figure 5 is an enlarged transverse sectional view taken substantially along the line 5-5 of Figure 3;

Figure 6 is an enlarged fragmentary perspective view of the foot end of the lift frame and corner of the bed, and

Figure '7 is a perspective view of the supporting hook for the foot end of the lift frame.

Referring to the drawings in detail, a bed designated generally H3 is equipped with the conventional head board I i and foot board l2 joined by conventional side rails 13 between which is pivoted as at i l intermediate their ends the trunk elevating frame !5 of the bed. The frame [5 is raised and lowered by conventional elevating mechanism It operated through the medium of a, hand crank I? which is generally located at the foot of the bed. The structure so far described is conventional with hospital beds and resting on the bed frame is a conventional jointed spring [8 and jointed mattress l9.

My invention embodies a lift frame or a horizontal limb supporting section designated generally 28 which comprises side rails 2| held-in spaced parallel relation at opposite ends by telescopic end bars or rails 22 which are held after adjustment against longitudinal movement by suitable set screws 23. As illustrated, the side rails 2| bend downwardly as at 24 near the head end of the bed so that opposite ends of the telescopic end bars 22 at the head end of the bed will rest directly on the side rails 13 of the bed frame. Secured as by clamps 25 to the foot posts of the foot 52 of the bed frame It are supporting hooks 26 carrying arms 27 with upturned hook members 28 at their free ends. The arms 2! form supporting elements for the telescopic cross bar 22 at the foot end of the bed so as to compensate for the downturned portions 24 at the head end of the bed in holding the patient level.

Attached to opposite ends of the extensible bars 22 are upwardly extending brackets 29 carrying at their upper ends eyes 36 to which hoist cables are adapted to be coupled for lifting the lift frame.

Pivoted as at 3| to each side rail 2| intermediate its ends is a side rail 32 of a trunk supporting and elevating frame designated generally 33. The ends of the side rails 32 of the frame 33 remote from the pivots 3| are joined by an extensible cross bar 34 which corresponds to the cross bar 22 at the head end of the bed and is held in adjusted position by means of set screws 35. As illustrated in Figure 4 when the frame 33 is in lowered position the cross bar 34 lies directly on the cross bar 22 at the head end 3 of the bed, with the side bars 32 of the frame 33 partially embracing the side rails 2| lying between the pivots 3| and the head end of the bed. As illustrated in Figures 2 and 3 the pivots 3! are substantially coincident with the pivots M so that as the frame l5 of the bed is elevated by the elevating mechanism 16 operated from the crank [1, the frame 33 will swing upwardly as suggested in Figure 3. In order to hold the frame 33 in elevated position I pivotally attach as at 36 to each side rail 32 near the cross bar 34 an arm 3'! provided with spaced notches 3B which are adapted to receive laterally extending pins 39 carried by the side rails 2| near the head end of the bed. It will thus be seen that as the frame 33 is elevated the pins 39 may be entered into the various notches 38 so that when the lift frame 20 is lifted from the bed, the frame 33 will stay in the position selected.

In order to support a patient on the lift frame when it is elevated from the bed I provide a lift sheet 40 which extends transversely of the lift frame and across the top of the mattress l9 from a point adjacent the foot of the bed to a point near the pivots 3 I. A similar lift sheet 4i extends transversely across the lift frame from a point near the terminus of the sheet 49 to the head of the bed. One side edge of the sheet 60 is anchored as at 42 to a side rail 2| while its opposite edge is detachably secured as at 43 to the opposite side rail 2|. The sheet M is likewise anchored to the frame 33 and it will thus be seen that when the lift frame is elevated from the bed and mattress 19, the weight of the patient will be sustained on the lift sheets.

In use the frame is deposited on the bed as suggested in the drawings and the end bars 22 and 34 are adjusted properly to support the frame on the side rails l3 and supporting hooks 26. The trunk supporting and elevating frame 33 will of course be deposited toward the head of the bed so that the pivots 34 coincide substantially with the pivots [4. A patient may then be placed on the bed in the ordinary manner and when it is desired to elevate or transfer him for any purpose, it is only necessary to couple suitable elevating cables to the eyes 30 and lift the frame and the patient clear of the bed so that his weight is supported on the lift sheets 40 and 4|. If the patient is in a sitting posture when it is desired to lift or transfer him the notched bars 3'! are adjusted with relation to the pins 39 so as to sustain the frame 33 at the desired angle and the patient may be lifted without altering his position. Likewise the patient may be replaced on the bed without changing his position and when it is desired to raise or lower the frame 33, the arms 31 are disengaged from the pins 39 so that the frame 33 will rest on the frame l5. The raising or lowering of the trunk of the patient may then be accomplished by merely turning the crank l1 and he may be gently returned to a prone position without suffering any serious discomfort.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described this claimed as new is:

In a hospital bed of the type which includes a bed frame embodying a horizontal limb supporting section, and a trunk supporting and elevating section pivotally connected to the limb supporting section to move upwardly in a vertical are from a horizontal position aligned with the limb supporting section, and means carried by the bed frame and connected to the trunk supporting section to move said trunk supporting section through said vertical are, means to support a patient so that-when the bed is moved the patient is held in a position substantially identical with that occupied by him while on the bed, said means comprising a lift frame adapted to rest on the bed frame, a trunk supporting and elevating frame pivoted to the lift frame adjacent the pivotal connection between the limb supporting sections of the bed frame and the trunk supporting section thereof, so that said trunk supporting and elevating frame is arranged to move in a vertical arc with the trunk supporting and elevating section, said trunk supporting and elevating frame being adjustably connected with the lift frame to hold the trunk supporting and elevating frame in elevating position during the removal of the lift frame from the bed frame, and lift sheets carried by the lift frame and the trunk supporting and elevating frame, said sheets overlying a mattress supported on the bed frame and supporting a patient on the lift frame when it is removed from the bed.
